Abstract
Car-based volunteer driver programs have emerged as important providers of transportation in many rural and low-density locations in which automobile dependence is high and transit access is negligible. The degree of this importance is not known, yet it can be expected that demand for these services will increase commensurate with the transportation needs of the aging population. The challenge remains that there is limited technical guidance for existing and new programs to anticipate and respond to the anticipated increases in travel demand from an aging population. It is also unclear how these programs can fit into transportation engineering and planning. This paper presents aggregate results of travel data collected for one year using a uniform data reporting approach by seven car-based volunteer driver programs in New Brunswick, Canada. Users 65 years and older accounted for 49–65% of members, and programs on average made 2.0 stops (trip end) per drive (trip chain), drove 39 km per stop, 61 km per drive, and had an occupancy of 1.5 riders per drive. A total of 88% of drives had 3 or fewer stops, and one drive was cancelled for every 10–11 offered. A total of 49.3% of all stops (excluding home) were for health purposes, with 20.7% for education/work. Seasonal, daily, and hourly trends were observed. Volunteers in groups with <100 riders provided more hours/drive but fewer hours/year than those in larger groups. These data can provide a basis for a more sophisticated approach to program planning and could be useful in forecasting for future demand.
